Nia vibrissa is a species of fungus in the order Agaricales. The species is adapted to a marine environment and is a wood-rotting fungus, producing small, gasteroid basidiocarps (fruit bodies) on driftwood, submerged timber, mangrove wood, and similar substrates. The spores have long, hair-like projections and are widely dispersed in sea water, giving Nia vibrissa a cosmopolitan distribution.

Taxonomy

Nia vibrissa was originally described in 1959 from submerged wood off the coast of Florida. The Latin epithet "vibrissa" (meaning "bristly") refers to the hair-like appendages on the spores. It was initially thought to be a deuteromycete (an asexual or mould-like fungus),[1] but was subsequently found to be the sexual state of a basidiomycete, one of the few such known from the marine environment.[2] Since its fruit bodies are enclosed and its spores are passively released, Nia vibrissa was considered to be a gasteromycete and was placed in its own family within the Melanogastrales, a now obsolete order of terrestrial false truffles.[3]

DNA sequencing has since shown that the species is actually related to species of cyphelloid fungi and agarics within the Agaricales.[4]

Description

Fruit bodies are more or less spherical, yellow-orange to orange-brown, 1–4 mm across. The remarkable spores are oval, 10–15 by 6.5–8.5 μm with 4–5 bristle-like appendages up to 40 μm long.[1]

Habitat and distribution

The species is widely distributed in the Atlantic Ocean, the Mediterranean Sea,[5] the Indian Ocean, and the Pacific Ocean.[6]

Nia vibrissa has been shown to be a wood-rotting species[7] and was first obtained by leaving wooden "baits" in the sea, retrieving them after a period of time, and then examining them in the laboratory.[1] Other records of the fungus have come from a similar methodology, but it has also been found widely on dead mangrove wood[6] and on natural driftwood. Fruit bodies of the fungus were found on wood salvaged from the wreck of King Henry VIII's 16th-century warship, the Mary Rose.[8]
